Ben.
There is a 13 sector version of ADTPro. All you
need is a working
Apple II or IIe with a floppy drive and serial card (or ethernet
card). It can even bootstrap the Apple into 13 sector DOS 3.2 mode
and then you can read and transfer disk images to a PC via serial or
ethernet. Then use CiderPress to read the files from the disk
images.
Jim Sather's "Understanding the Apple IIe" has a wonderful exposition on
the workings of the Apple II disk controller. Without having an Apple
II at my disposal in the 80s, I was able to construct a rather simple
ISA card for a PC that would read Apple floppies.
Then I got a MatchPoint PC card.
Now, of course, handling Apple II floppies can be done with $3
microcontroller card.
